there's only one way to prove the percentage of bikes as commuters in today's matier and ross column- make them register their "vehicles". of course that might lead to fees and fines and insurance and liability . until then their self-counting is patently bogus . currently i think there are more little painted pictures of bikes on our sreets than actual bikes. take for instance the new forced merging lanes on sloat blvd.- it's caused more traffic congestion where there was none before- all for the phantom bikultists that aren't there.
